Electronics & Electrical Stamping Solutions

LIHAO provides electronics and electrical stamping solutions for manufacturers producing terminals, connectors, shielding parts, relay components, electrical contacts, motor components and other precision metal parts.

Electronic and electrical components are often produced from thin copper, brass, stainless steel or other metal strips and require accurate feeding, stable material flatness and reliable synchronization between the feeder, press and progressive die.

LIHAO can integrate stamping press feeders, precision straightening equipment, high-speed presses and stamping dies according to the material, part drawing, feed pitch and required production speed.

Typical Electronic & Electrical Stamped Parts

Our stamping equipment can be configured for the production of:

● Electrical terminals
● Connectors and connector shells
● Terminal pins
● Relay brackets
● Electrical contacts
● Shielding cases
● Metal clips and springs
● Switch components
● Battery contacts
● Electronic brackets
● Motor and electrical components
● Precision small metal parts

For components manufactured with progressive dies, accurate strip feeding is especially important because multiple punching, blanking and forming operations are completed continuously within the same die.

Materials for Electronics & Electrical Stamping

Common coil and strip materials include:

● Copper
● Brass
● Phosphor bronze
● Stainless steel
● Cold rolled steel
● Galvanized steel
● Aluminum
● Thin precision metal strip

Thin materials require careful straightening and feeding because excessive roller pressure or unstable tension can cause deformation, scratches or inconsistent positioning.

LIHAO offers different sheet metal straighteners for thin and precision materials, allowing the straightening configuration to be selected according to thickness, width and material properties.

Key Challenges in Electronics & Electrical Stamping

Precision Feeding for Small Components

Terminals, connectors and electrical contacts usually have small dimensions and short feed pitches.

Even small feeding deviations can affect:

● Hole position
● Terminal dimensions
● Bending position
● Connector fit
● Progressive die alignment

A NC Servo Roll Feeder provides programmable feed length and repeatable material positioning, making it suitable for precision coil-fed stamping applications.

Thin Strip Straightening

Copper, stainless steel, brass and other thin strips may retain coil set or develop deformation during material handling.

Before entering the press, the strip should be properly straightened while avoiding unnecessary surface damage.

For electronic parts using particularly thin material, the feeder and straightener should be selected according to the actual thickness range rather than using equipment designed for general medium-gauge sheet metal.

High-Speed Continuous Stamping

Electronic terminals and connectors are commonly manufactured in large quantities using progressive stamping.

In these applications, the feeder must synchronize with the press cycle and maintain consistent feed pitch during continuous operation.

LIHAO's press machines can be integrated with feeding equipment and dies to form an automated stamping line.

For higher-speed precision applications, the SYG Series Closed Double Point High-Speed Precision Punch Press can be used for applications such as electronic connectors, terminal pins, shielding cases and other precision components.

Surface Protection

Electronic components often use copper, brass, stainless steel and coated materials with relatively high surface-quality requirements.

Improper coil handling, roller pressure or material alignment can cause:

● Scratches
● Roller marks
● Strip deformation
● Edge damage

The feeding system therefore needs to maintain stable material guidance and suitable roller pressure throughout continuous production.

Recommended Electronics Stamping Line

A typical electronic component stamping line can be configured as:

Coil → Uncoiler → Precision Straightener → Servo Feeder → High-Speed Press → Progressive Die → Finished Parts

LIHAO provides uncoilers, straighteners, feeders and presses that can be selected according to coil weight, strip width, thickness and production speed.

For applications where a compact integrated feeding system is preferred:

Coil → 3 In 1 Straightener Feeder → Press → Progressive Die

However, for very thin and narrow precision strip, a separate uncoiler, precision straightener and servo feeder configuration may provide greater flexibility for material handling and adjustment.

Progressive Die Stamping for Electronic Components

Progressive stamping is widely suitable for components requiring multiple operations and large production volumes.

A strip can pass through several stations for:

● Piercing
● Blanking
● Bending
● Forming
● Cutting
● Part separation

LIHAO can match the feeding system and press with a customized Progressive Die according to the finished-part drawing and stamping process.

For precision electronic components, our customized progressive dies for metal stamping can be integrated with automatic coil feeding equipment for continuous production.

How We Configure Your Electronics Stamping Line

The appropriate equipment configuration depends on the actual component rather than only the industry.

Before recommending a stamping solution, we evaluate:

● Finished-part drawing
● Material type
● Strip thickness
● Strip width
● Coil weight
● Feed pitch
● Required stamping speed
● Press tonnage
● Die structure
● Required production capacity

For example, a thin copper terminal strip may require a very different feeding and straightening system from an electrical enclosure or motor component.

LIHAO therefore selects each component of the production line according to the actual stamping process.

Why Choose LIHAO for Electronics & Electrical Stamping?

LIHAO specializes in coil feeding and stamping automation equipment and can provide both individual machines and integrated production lines.

Our supply scope can include:

● Uncoiling equipment
● Precision straightening
● Servo feeding
● High-speed stamping presses
● Progressive dies
● Press and feeder synchronization
● Production line integration
● Installation and commissioning
● Operator training
● Spare parts and after-sales support

By matching the feeder, press and die around the same production requirement, manufacturers can reduce equipment compatibility problems and build a more stable continuous stamping process.
